On the outer end of countershaft. 39 are l lOunte'd the double cam-disks 23 24, provided with cam-grooves 25 25, engaging a roller on theinner cnd'sjoi' the clutch-shifting rods 219.77 duntedjnssu bl sl d glwwfi s 28. The grooves are so vdisposed as ,to throw the clutches into engagcment with the pinions 16 and into positions-ofrestat such times as to transmit niotion through the shafts 13 and 14 whefnrcquired and to permit the shafts and their dependent mechanism to remain at rest whenyequired. j Mounted entire-top of the cross-head I3 is the carriage 29, which traverses the length of the cross-head from end to eiid, accomplishingin its travel the distribution of thecrosswires, as shall heherei'nafter described. This forward-and-hnck travel of the carriage occurs'wh'en the other operative partsofthe maehine are at rest and is caused by a sprocketwheel 30,31103 nted on rhe end'gi sh tit. 1 3, act- .aetion.oiTbevel-gearing 1516, the time of operative contact of the gearing being controlled by the groove 25, acting through rod :27.

io5 pin lat, extending at right'an'glcs from the to The-bolt so spaced at' gradtruly-increasing distancesapart as todistrihnic the horimntal wires tomalic a fence with close strands atone side and moreopcn toward the opposite side. All of the bolts it are disengagedsimultancously by means of lifting-paddles 50, mounted in a rock-shat t 5! and adapted to engage pins 52 in eaeh'slidc. The l'oclI-ShtlQE ls intermittently related a partialrownniion by means 7 oi. an a rm 5-3, acted upon by pins 5i of a wheel 5 mounted on the cam-shalt :36, the rockshaft being returned to its original position immediately by spring action, the bolt 40 in the meanwhile remaining out of engagement during the entire rotation of the twister-head and'th'o shaft being retained in position by the holding action of the loop a. The carriage is caused to traverse the cross-head from end to end under action of chain Ill through intermittent motion 0t" driving sprocket wheel 30, the motion of the sprocket-wheel being controlled by the length of time the forwardor reverse pinion 10 isin engagement with the gear-15, which period of engagement is controlled by the cam-groove 25 and of suilicient duration to accomplish the full travel the carriage. The arriago is mounted on the cross-head by me:-

of do etail slides, and at one side, projecting over the line of knots, is a boss 57, within. which is mounted, with intervening rollers 58, a hub 59, to the upper portion of which is secured a pinion GO,-ha-ving a vertical passagetl, through which the cross-wire is introduced to the looping-needle 62. This needle is likewise hollow for passage of the wire andprojccts downwardly through the 59 at an angle from the perpendicular hin close proximity to the twister-shafts 'ateiy beyond the ends of such cross-bar C- rigidly secured tothe l= n which is the tension-needle in inch is mounted the tension neeprojecting up through holes in bar 15;}, slightly beyond the line of twisting-pins and spiteed between them. The needlehar 6+. is mounted at each end upon arms 66, pivoted to cross-shaft G7, and the arms terzninato in upper and. lower spanner-s (i8 69, the uppcrof which, 68, hears upon the upper edge of cam-wheel on shaft 56. The lower spanner 69 projects into the path of pins 71, and the cam-wheel is pro Med with corresponding depressions, so as to permit the spanner G3 to fall when the pin engages the lower spanner, while the raised portions of the cam reverse the motion and lift the arm. liy this means the pins 65 are withdrawn below the level of bar 03 in he action of releasing the cross-wire from tension andarc then returned to the raised position.

Mounted on a stud 72 is a toothed wheel 73, in mesh with the pinion GOand of a diameter four times that of the pinion-wheel 60, so that by oiiequarter revolution of the drivingwheel the pinion, and consequently the looping-needle (32, will be caused to make one complete revolution. In the travel of the carriage the needle makes one revolution around each twister-pin 44, and in its outward sweep travels around each of the tension-needles 65, distributing the cross-wirc-, as indicated in dotted lines in Fig. l-l. The action oi the needle is intermittent and is produced by a ruelehar 7-l mounted in the. eress-head, having isolated teeth 75 at ntuitionscorrespond ing to each twister,

toothed gear-wheel, mounted on the stud 72, by which means the stud is caused to rotate witl'i which teeth inter- 'mesh one ofthe series 76 of a mutilated one-quarter revolution for each set of teih 75, producing the entire revolution of the needle 62. For the purpose of checking mo mentuni and positively controlling the action of the stud a'square cam-77 is secured to or formed integral with the stud, which cam has a hearing along the inner face of a guidingplate 79, set above the rack-bar Tl and reecssed at 79 to permit the cam to turn under action of the gearing.

7 At each endof the cross-head are located the shearing-grippers A A, which cut 0d the wire, leaving a projecting end protruding from the looping-needle, as in Fig. 16, and grip it until released by retraction of the grip. The stationary portion of the gripper consists of a base-80,;bolted to the frame in which is mounted the gripping-die 81, having a serrated face and an edge 82, against which the Wire is sheared. the end of a bar Si, slidingly mounted in a housing 85, bolted to the crossbar G3 at each end. The bar is actuated through a rod 80, having a hearing at the under side of the erosshead and an upturned end in engagementwith the bar. The rod and shear-bar are thrown backward from engagement with the grip by action of a cam 87 on shaft 56, which cam is provided with release -faces bearing on dog 88 and so located as to permit the rod to fly forward under action of spring 89 when released,'sovering the wire and firmly gripping its end until again released.

Secured to the base 80 are fender-plates 90, against which the projecting end of the wire bears in its next forward movement due to the travel of the carriage, the end projecting between the vertical plate and a dowmvardly-I projectingabutment'91 and against a sharp corner 92, by which it is tightly held against the strain of the'departing needle, the wire in the meantime passing around a guiding grooved shoulder 93 and across the face of grip 81.

Spring-plates ill 95, the latter pivoted and adapted to open for entrance of the end of the needle, assist in controlling the direction .of the projecting wire end, which is finally out olf and drops down as waste.

The operation of twisting the loop and form ing the knot is'more clearly illustrated in Figs. 51 to 5d, inclusive. The cross-wire having been disposed around the pins, as has been shown, the 'strand-wires' are thrown around the loops formed on the pins 4% in one- -revolutiou, and the loops and strand-wires.

are then given a one-half revolution, when the knotted loops are removed downwardly from the pins, and the pins and twister-shafts are hen given a one and one-half revolution without performing any work in. order to bring them to the correct position for the next opereuhn in the reverse direction. This intermittent motion is imparted to the twister-s by means of a rack 90, mounted in the crosshead, in engagement with teeth 97 of each twister-head and with a single driving pinion-wheel OS on shaft 09, to whichmotion is imparted in both directions, respectively, through.bevel-gearing lOlhshaft 101, and

' bevel-wheel 102, actuated'by the toothed difl'e'rential gong-wheel 103 and its accompanying niechanispi. Immediately before rotary motion is imparted to the twist cnhead 11 the 1 lockingdiolt 1'0 is withdrawn from engage- .inomentarily remain at rest until the section of fence is witl'idrawn, when the remaining one and one-half revolutions will he made,

the twister operating idly, and the parts are then in position for another operation. This intermittent action of the twister is accoin-.

' plished through thedifferential gear-wheel 103. (More t'ully illustrated in Figs. 45 to 50, inclusive.) The gear-wheel 103 and a fender-wheel 101 are rigid]; keyed on the shaft 1-1, to which intermittent motion is impar-ted ns hashdulLtESlQl' gq, gh gearing 10 17 in a forward-and-backdirectional ternately. The pinion gear 1' wheel 102 is keyed on shaft 101 and is adapted to intermesh with the series of teeth 105 and to retate when sovin mesh and to reniainstationary when occupying the spaces 100 106'--be tween such series, the bevel-pinion normally occupying the position of rest, as shown at space 100'.

The blank space 106 is diametricallyopposite space 106 and the teeth are so proportioned that the 'pinion will make just one and onehalf revolutionsin traversing one of the series of teeth 105, transmitting niotionto the'twisters and producing the first one and-ene-helf revolntrons, as has been. described, onc revolution of the twister-head alone and one-half revo-. lutlon lLl engagement with the shaft- 43.

The time occupied by the blank 106 in passing without engagement is utilized to withdraw the knots, the pins 11 being turned down, and the various parts are held against n oyemcnt due jto noinen'tum, and the position of the pinion with relation to the next engagementof the teeth is controlled by a somewhat longer vanrnlatc 109, secured to the blank l'einler-whecl oppos e the space 100 and provided with graduajlyesoending faces cor-re the shoe 108 rides. order to-insure proper engagement 'ofthejteeth for the next halfrevolution ofwheel 103, it is necessary to cause a slight retrograde movement ottho pinion just sufficient to cause the tooth last in engagement with the departing section to be the first to engage the oncoming section of triggers 110, pivoted to the plate 109,11or

At each side the projecting endof the crosswire after being cut is drawn down for one section of fence, when it comes into range of the end-twisters, by which the free ends are neatly twisted around the bntside strandwires, as shown in, Fig; 38. This is accomplished by actio'nof .the sprocket-wheel. 30 during travel of the carriage when the fence isstationary in itspassage through the machine.

A downwardly-projecting stem 136 is formed integral with the twister and is provided'with the cross twister-fingers 137, which in the rotation of the twister engage the free end of the wire and wrap it around the strand. The twisterpinions 134 are rotated forward or back by rack 138, mounted in the brackets 133, provided with an actuating-pin 139, projecting downwardly through slot 132 and adapted to engage a slotted angle-plate 140, secured to a horizontal bar 141, also mounted in the bearings 120. Secured to. the bar 141 is a downwardly-extended arin142,havin g a central slot 143, the inner edges of which are outwardly beveled at the bottom. Into this slot enters the roller 144, mounted on a bracket 145, so-

cured to the sprocket-wheel 30, and by which the bar 141 is carried forward and back at each forward and back rotation of the sprocketwheel. Normally the twister-pinions are held away from engagement with the wires during the downward travel of the fence by the lever 122, as shown in Figs. 30 and 31, the pin 139,

being held out of engagement with slotted plate 140 until the shaftl3 is actuated, when the plate 131 and its supported mechanismwill be thrown down into operative position, ongaging the wire' end at the same time that the parts are thrownin to position for operation.-

The finished fence is drawn downwardly under tension by a feeding-drum 146, mounted on shaft 147, the tension of the drum-drawing the strand-wires through the passages 40 in the twister-heads, and the finished fence 'is wound into a roll on a double bar 148, constitutingawinding-drnm,supported in brackets 149 on the inner ends of short shafts 150,

mounted in hearings in the ends of the side frames. it is desirable to rotate the bars 148 sufiiciently far to wind upon them the whole, feedof the machine at all stages of its progress and to graduate the amount of winding to the increasing diameter of the roll; also, to transmit such motion at a time when the other functions'of the machine are inoperative, and the winding of the fence upon the reel and the operation of the feed-drum are accomplished within a fraction of theentire operation-of the machine by the followingdescribed mechanism: To the outer end of main shaft 7 is secured a pinion-wheel 151, inter-meshing with a toothed gear-wheel 152, loosely mounted on the end of shaft 18, the diameters of the two wheels being regulated so as to produce a sufficiently-slow movement of the wheel 152.

Mounted in the framework and in suitable bearings is a counter shaft 153, having a toothed gear 154 meshing into a similar gear 155 on the shaft 147 of the winding-drum. On the outer end of the shaft 153 is secured a ratchet-wheel 154', with which engages a pawl 15e, mounted in arms 156, at the upper end of which is a roller mounted'on a cross-pin 157. A pitman 158 is secured to a for adjustment of throw, and the outer end is slotted to permit of considerable lost motion, the slot engaging the roller and pin 157. By this means it will be seen that at a portion only of the revolution of wheel 152 will motion be transmitted to the ratchet-wheel and through the gearing to the winding-drum, such operation occupyihg but a comparatively-limited time. Upon the shaft 153 is keyed a sprocket-wheel 159 of considerable diameter, connectedby chain 166 to a smaller sprocket-wheel 161, mounted loosely on afriction-disk .162, ke'yed' to -a cross-shaft 163, mounted in hearings in the side frames. Outside of the wheel 161, mounted loosely on the-shaft 163, is a sprocket-wheel 164, upon the hub of which bears a coiled spring 165, adapted to be set against the wheel with considerable pressure by nut 166'. Iutervening betweenthe friction-disk friction-washers 167, of leather or other suitable substance, and when the parts are brought together with sufiicient pressure motion will be transmitted. from whecl161 through the friction-washers to wheel 164 and fromsuch wheel through chain 168 to means the reel-shaft will be rotated until the slack is wound up on the reel, when any furslippage between the friction-washers. The action of the winding-drum is positive, and its diameter and amount of travel will-accurately regulate and control the amount of feed of the fence at each operation.

sprocket-wheel, as in Fig. '41, an idle pinion '170 may be inserted between and 155, so as to secure proper direction of rotation. It will be observed that the pull on the ends of the reel-shafts isequalized by the employment of sprocket-gearing at the other side of the machine, as shown in Fig. 1. 7 The operation of the machine will be readily understood from the foregoing description.
